Abstract: A taxonomical note on Caragana kansuensis Pojark. and other confusable taxa is presented in this paper. C.kansuensis Pojark. and C.brachypoda Pojark.should be treated as two distinct species. The plants from North Shaanxi Province, Northwest Shanxi Province and other neighboring areas which misidentified as C.kansuensis Pojark., in fact, should be a new variety of C.opulens Kom. named C.opulens Kom. var. angustifolia Y. Z. Zhao ex Zhao. Y. Chang et F. C. Shi. The new variety is different from C.opulens Kom. var. opulens by its narrow and dense pubescent leaflets, which often becoming reddish on lower surface when dry. It is also similar to C.licentiana Hand.-Mazz., but distinguishes from it by long petioles, long and narrow leaflets and nearly glabrous fruits.

Key words: Caragana kansuensis Pojark., C.brachypoda Pojark., C.opulens Kom. var. angustifolia Y. Z. Zhao ex Zhao. Y. Chang et F. C. Shi, confusable taxa
